FILE - In this Wednesday, July 3, 2013 file photo, an employee feeds a camel a carrot at the Camelicious milk farm in Dubai, United Arab Emirates. Scientists have found a clue that suggests camels may be involved in infecting people in the Middle East with the MERS virus. In a preliminary study published on Friday, Aug. 9, 2013, European scientists found traces of antibodies against the MERS virus in dromedary, or one-humped, camels, but not the virus itself.
